| Abstract: | Two synthetic cyclic oligomers of polyaryletherketones were studied by matrix _ assisted laser desorption ionization-time _ of _ flight mass spectrometry(MALDI-TOF-MS). The distribution of oligomers with different degrees of polymerization is discussed. Experimental results show that MALD-TOF-MS is a direct, accurate and rapid method for the characterization of cyclic oligomers. |
